ABSTRACT:
An assembly of a pair of magnetic transducers held in substantial contact with a flexible magnetic disk wherein each transducer has a pair of disk contacting lands broadening in contour toward the trailing end of the transducer and tapering in contour toward the leading end of the transducer, with the leading and side edges of each land being gradually blended into the surrounding active surface of the transducer and with the trailing edge of the land being sharp. A first one of the lands of each transducer has the read/write magnetic gap in it, and this land is located opposite the land of the other transducer not having the read/write gap in it which is wider than the first land. The centers of the opposite lands are in alignment, and the centers are measured on a plane passing through the read/write gaps of the transducers.
